“Exactly what my current system was missing. Love the midrange dynamics, and how smooth these tubes run.”

“I REALLY like these tubes!!! Especially if I just want to sit down and enjoy my music, and not nit-pick as to whether I can or can't hear the tension of the rosin on a violin bow or not.... That being said, these tubes are SOO clean and smooth.... They are actually comfortable.... While I can't say the sound stage is as good as a long-plate; Cymbols will resonate and naturally fade as opposed to only hearing the stick hit. I am pairing these tubes with a CV4024 in the 12at7 spot.. JD”

“These are the tubes for me. Detailed, but not harsh. Bass lines one can follow. Well suited for all kinds of music. Found them by tube rolling. I have a backlog of them now. Hope I never run out.”

“I replaced the stock tube in my Bellari PA555 with this tube. The stock tube is good but I wanted to soften the upper midrange and this tube accomplished that. Very happy with this purchase.”
